パラメータ


3A LED driver, Wide 5V to 36V Operating Input Range, Hysteretic Control, Short LED protection

The MP2480 is step-down switching regulator that delivers a constant current of up to 3A to high-power LEDs. It integrates a high-side, high-voltage power MOSFET with a current limit of 4.3A. The wide 5V to 36V input range accommodates a variety of step-down applications, making it ideal for general lighting and LCD backlighting applications. Hysteretic current-mode control helps provide for a very fast response, which makes the 20kHz dimming frequency possible. MPS’s proprietary feedback control minimizes the number of external components while delivering an LED current with a typical accuracy of ±3%. The switching frequency goes up to 2MHz, thus permitting smaller components. Thermal shut down, and short circuit protection provide reliable fault-tolerant operation. A 160µA quiescent current allows for use in battery-powered applications.  The MP2480 is available in SOIC8-EP with an exposed pad on the bottom.
